Human Stem Cell Use: iPS Cell
Immune cloaking of human stem cell-derived insulin-producing cells for curative cell therapy without immunosuppression
Research Objective The goal of our project is to generate cells for replacement therapy in patients that have reduced ability to trigger the immune response in the recipient and therefore escape rejection. Impact We test a novel molecule that reduces immune activation upon transplantation of allogeneic stem cell products that can improve graft survival and […]
Modeling of GATAD2B-associated neurodevelopmental disorder and NuRDopathies: Investigation of cellular & molecular anomalies altering neurodevelopment
Research Objective Human and animal models of NuRD-deficiency will identify NuRD-subtype function in context of neurogenesis. Multi-omic studies will identify/quantify molecular and cellular changes in NuRD-deficiency. Impact NuRD-deficiency causes several neurodevelopmental disorders (NDDs), our work will identify and quantify cellular and molecular changes in human and mouse models of corticogenesis with NuRD deficiency. Major Proposed […]
Village-based identification of human risk factors for viral neuropathogenesis
Research Objective We will identify the risk factors underlying viral infections of the fetal brain using a novel human stem cell-based platform that has the potential to accelerate basic and translational discoveries. Impact Our work will identify the biological factors that influence inter-individual differences in susceptibility and immune response to neurotropic viruses, which could inform […]
Utilizing Age-Specific Adipocyte Progenitor Cells for Cell Therapy in Older Patients
Research Objective A new type of APC serves older patients as 1) better MSC in immunomodulation (reducing inflammation) for autologous transplantation; 2) better source of somatic cells for generating heathier hiPSCs. Impact Bottlenecks: 1) Older patients suffer from sarcopenic obesity, which has no safe and effective treatment. 2) Cell therapy in older patients is often […]
Modeling and understanding alveolar hypoplasia in Down syndrome using iPSCs-derived alveolar type II cells
Research Objective Understanding alveolar progenitor cell defects in T21 and the genes/pathways associated with them will allow for developing therapeutic approaches for individuals with DS. Impact Although trisomy 21 affects multiple organ system, respiratory complications are the major cause of death in kids and adults with DS. The causes of lung disease in DS remain […]
hPSC-derived enteric ganglioids for cell therapy in gastrointestinal motility disorders
Research Objective The proposed aims will enable the generation, purification and characterization of enteric neurons from diverse hiPSCs and assessment of their efficacy for cell therapy in GI motility disorders. Impact This proposal addresses a significant unmet clinical need for a cell therapy approach for gastrointestinal motility disorders such as Hirschsprung disease, achalasia and gastroparesis. […]
Defining the source of dysfunction in monogenic Intellectual Disability Syndrome neurons
Research Objective This study will use pluripotent stem cells derived from patients to determine why Intellectual Disabilities caused by mutations in chromatin regulatory proteins leads to neuronal defects. Impact Our study of intellectual disability syndromes will determine links between mutations and neuronal dysfunction Major Proposed Activities Our study of intellectual disability syndromes will determine links […]
Characterization and applications of human blastoids for understanding early human embryogenesis
Research Objective Our work will yield an improved stem-cell based embryo model that we will explore with various omics approaches and genetic screens to gain insights into the pathways that control human embryos. Impact An improved stem cell-based embryo model is a crucial step for in-depth studies of human development and will enhance our ability […]
Role of ataxin-3 polyadenylation site selection in ALS neuron toxicity and disease pathogenesis
Research Objective Here we will study the role of ataxin-3 alternative polyadenylation in the pathogenesis of ALS, and test if ASOs can reduce distal polyadenylation of ataxin-3 to rescue ALS disease phenotypes Impact Our goal is to determine if ataxin-3 genetic dysregulation is a target for the development of therapies to treat ALS (Lou Gehrig's […]
Modeling Retinitis Pigmentosa using patient-derived human iPSC organoids
Research Objective The objective of this proposal is to develop a human retinal organoid model of adRP to gain insights in pathogenesis and assess clinically relevant approaches to restore RHO protein function. Impact Upon successful completion of this study, we will have established a disease-in-a-dish model and a novel therapeutic approach towards management of the […]
